There is a type of conductive paper (graphite impregnated) used in physics
teaching to demonstrate cross sections of electrostatic fields by 
analogy......also, any rubber compound can be made conductive by including
enough graphite (latex will take its own weight of graphite as filler I
believe).

reminds me of the Hugh Le Carne(?spell) Electronic Sackbut which used a puck 
shape to couple capacitively to several pie sections on a surface as a mixer..
of course Le Caine(?spell)  was canadian hence the puckish approach ;)

If I am very wrong on this ancient emusic history I hope DAC will put me right
